SIG SAUER is conducting a mandatory replacement of the carriage assembly, in SIG MCX rifles. SIG has found, through extensive factory testing, that in extremely rare instances, not reported in the field and extremely difficult to replicate, a condition may exist causing an unintended discharge. Failure to follow the loading procedures and basic rules of safe firearms handling, as outlined in the user’s manual, has the potential to cause serious bodily harm or death. Although this has only been witnessed in 300 blackout, SIG has decided to upgrade all MCX models, since the MCX is a modular platform and they want to ensure the quality and reliability of all products they manufacture.Get more info: https://www.thetruth...all-mcx-rifles/
